Key Takeaway Key Takeaway: MSCT with enhanced imaging and 3-D reconstruction can enhance the accuracy of preoperative CTNM staging of gastric carcinoma, guiding treatment planning and potentially becoming a primary method in diagnosis.
Abstract
Objective:To evaluate the diagnosis value of MSCT for preoperative CTNM staging of gastric carcinoma and provide the imaging evidence for surgical operation.Methods:Ninety-two gastric carcinoma patients were scanned on 8-slices spiral-CT including plain scans and dual phase enhanced scans respectively.The source images were performed three-dimensional reconstruction.The tumor location,bound,size,estimate surrounding tissue extension and regional lymph nodes metastasis were observed.The preoperative CTNM staging of gastric carcinoma was performed.Results:MSCT was a promising technique for detection and preoperative CTNM staging for gastric carcinoma,the accuracy of the preoperative CTNM staging of gastric carcinoma and preoperative dissection estimation were 91.3%,95% respectively.Conclusions:The combination of the enhanced MSCT and 3-D reconstruction of the source image can elevate the accuracy of the TNM staging of gastric carcinoma.The technique is valuable in guiding the treatment planning and may be used as a principle method in the diagnosis of gastric carcinoma.
